This research aims to design a stable, effective nanoparticle vaccine targeting both SARS-CoV-2 and MERS-CoV.
Utilized artificial intelligence for structural modeling of Helicobacter pylori ferritin (HPF).
Confirmed disulfide bond formation using cryo-EM in the optimized HPF variant (I69C).
Evaluated immune responses in hACE2 and hDPP4 transgenic mice post-vaccination with bivalent nanoparticle vaccines.
Bivalent vaccines elicited significantly higher RBD-specific antibody titers compared to monomeric and dimeric forms (exact figures not specified).
Increased frequencies of antigen-specific B cells and polyfunctional CD4+ and CD8+ T cells observed post-vaccination.
Two doses of bivalent vaccines provided protection against challenges from authentic SARS-CoV-2 and MERS-CoV.
